PHP to PDF Converter

Generating PDF files using PHP is a very common requirement in web applications.

Invoices, reports, certificates, receipts, and downloadable documents are usually provided in PDF format because PDFs preserve layout and work consistently across devices.

A PHP to PDF converter allows you to convert HTML content, text, or database data into a downloadable PDF file using PHP code.

What Is a PHP to PDF Converter?

A PHP to PDF converter is a tool or library that enables PHP scripts to:

• Create PDF documents dynamically
• Convert HTML pages into PDFs
• Generate printable reports from database data
• Download or email PDFs to users

Instead of manually designing PDFs, PHP converts existing content into a structured PDF file.

Why Convert PHP Output to PDF?

Using a PHP to PDF converter is useful when you need:

• Invoices and billing receipts
• Reports generated from databases
• Certificates or admit cards
• Downloadable documents for users
• Print-ready documents

PDF files ensure fixed layout, security, and professional presentation.

How PHP to PDF Conversion Works

The general flow is:

1. PHP collects data (from form, database, or API)
2. Content is formatted using HTML/CSS
3. A PDF library converts HTML/text into a PDF
4. The PDF is downloaded, saved, or displayed in the browser

This approach allows developers to design PDFs using HTML, which is easy and flexible.
